To 1/2 cup of Italian butter in a hot pan, I added about 30 sage leaves of all sizes that I had picked from the herb garden. I turned the heat down to simmer and cooked it for about half an hour until the sage leaves had shrunk considerably in size. I turned the heat up and watched it carefully until the sage leaves turned crispy and the butter turned light brown.
Using a very small strainer, I strained the butter from the leaves. I then used the butter on the pasta after it cooked.
